Furthermore‚ the module’s POINTBus current limits must be considered. It supports up to 1.3A for 1734 PDN chassis and 1.0A for 1734D chassis‚ preventing overload and maintaining system stability. Proper power supply selection and adherence to current limits are essential for optimal performance.
Technical Details
The 1734-AENTR features a wide input voltage range (10-28;8V DC) and varying current consumption based on input voltage (400mA at 24V‚ 800mA at 12V).
Input Voltage Range: 10-28.8V DC
The 1734-AENTR module demonstrates operational flexibility with its broad input voltage range‚ accepting power supplies between 10 and 28.8 Volts DC. This wide acceptance range allows for integration into diverse industrial environments with varying power infrastructure.
However‚ it’s crucial to note the corresponding current draw variations. At a nominal 24V DC input‚ the module typically consumes 400mA. Conversely‚ when operating with a 12V DC power source‚ the current consumption increases to 800mA.
Proper power supply selection is paramount to ensure stable and reliable operation. Exceeding the specified voltage range or insufficient current capacity can lead to module malfunction or damage. Furthermore‚ the module incorporates an isolated DC/DC converter‚ transforming the input 24V DC to an internal 5V DC for internal circuitry‚ enhancing system robustness and safety.
Current Consumption: 400mA (Nominal 24V DC)‚ 800mA (Nominal 12V DC)
Understanding the 1734-AENTR’s current draw is vital for proper system design and power budgeting. The module exhibits varying consumption levels dependent on the input voltage. With a standard 24V DC power supply‚ the typical current consumption is 400mA‚ representing a power draw of approximately 9.6 Watts.
However‚ when utilizing a lower 12V DC power source‚ the current demand significantly increases to 800mA‚ resulting in a power draw of 9.6 Watts. This increase is due to the module’s internal DC/DC converter maintaining the necessary internal voltage levels.
It’s crucial to ensure the chosen power supply can consistently deliver the required current under all operating conditions. Insufficient current capacity can lead to erratic behavior or module failure. Always factor in potential current spikes during startup or heavy network traffic when selecting a power supply for the 1734-AENTR module.
POINTBus Current Limits: 1.3A (1734 PDN)‚ 1.0A (1734D)
The 1734-AENTR communicates and receives power via the POINTBus‚ a backplane interface within the Allen-Bradley POINT I/O chassis. It’s critical to respect the current limitations of the POINTBus to maintain system stability and prevent failures. These limits differ based on the chassis model used.
When integrated with a 1734 PDN (Power Distribution Network) chassis‚ the total current draw from all modules on that segment must not exceed 1.3 Amperes. Conversely‚ when used with a 1734D chassis‚ the maximum allowable current draw is limited to 1.0 Ampere.
Exceeding these limits can cause voltage drops‚ communication errors‚ and potentially damage to the modules or the chassis itself. Careful planning and current budgeting are essential when configuring a POINT I/O system with the 1734-AENTR‚ ensuring all connected modules operate within the specified current constraints.
